About Us

The Science Dictionary is a specialized science search engine that queries billions of the web's top science pages for scientific information. The Science Dictionary was founded in 2006 and has since processed over three million (3,000,000+) queries. Every month, we receive over 250,000 page views from over 40,000 people worldwide who visit our site to learn more about a particular science topic. The Science Dictionary has been featured as a trusted resource by numerous educational institutes (K-12 and higher education) in the United States, the United Kingdom, and Canada. Researchers, students, and professionals around the world use The Science Dictionary as their goto website for searching scientific information.
TSD vs. Google

The Science Dictionary leverages Google's tens of thousands of servers and enormous web index of over 13 trillion web pages to perform its search queries. On top of Google's search index, The Science Dictionary has implemented a filtering system that determines which websites are trusted, science websites and which websites aren't. In layman terms, every time you perform a search on The Science Dictionary, The Science Dictionary first accesses Google's 13 trillion page index to find matching pages. Then, we take the returned results and filter them so that only pages that are thematically matched with your search term are returned.
For example, if you search for the term "wave" on Google, you'll get a search result containing information about Google Wave, WAVE the company, a governent organization named Wave, and a news station named WAVE. As you can see, most of the information that Google returns isn't relevant to science since Google doesn't know if you're searching for wave in a scientific context or in a business context.
On the other hand, if you search for the same term "wave" on The Science Dictionary, you'll get a search page with relevant scientific information about waves in physics, neuroscience, geosystems...etc.
